The machines are self-elevating platform, enable the lift with the construction of high rise or fall, has attached to the frame, the use of the site scaffolding steel pipe and wall connection, thus eliminating the need to pull the cable wind rope, suitable for use in a variety of small construction sites, the effective improve the environment of the construction site. 
 Hoists with anti-fall safety and activities of the bumper (insurance door). Anti attached security sudden break in the wire cage, now hover on the beams of the wire rope breaking, where high standards of section To prevent the cage fell to the ground that the accident occurred. Installation activities in the cage at the bottom of the bumper, make the cage stay in the construction of the required floor loading boring out and arch on both sides of the standard section fixed on the bumper, (percent) scaffolding steel pipe combinations using the site, prevent the construction workers in the hanging cage loading and unloading of materials, the cage fell to the ground, construction workers in the hanging cage loading and unloading of materials, the cage fell to the ground, the occurrence of casualties, to make construction safer. 
 Jack-up platform with manual hoist, lift installation, demolition, increase or decrease the need for an external power, and effectively protect the personal safety of installation and construction, reducing the labor intensity of construction personnel.
